Answer:
Newton's Second Law tells us that the more mass an object has, the more force is needed to move it. A larger rocket will need stronger forces (eg. more fuel) to make it accelerate. The space shuttles required seven pounds of fuel for every pound of payload they carry.

Answer: then you’re not sick d u h
Explanation:
Answer:
According to wavelengths in descending order: C, B, D, E and A
According to frequencies in descending order: A, E, D, B and C
According to speeds in vacuum: A =B =C =D =E
Explanation:
in the EM spectrum, radio waves have the longest wavelength while gamma rays have the shortest wavelength.
All EM waves travel with the same speed of in a vacuum.
Answer:
F = 8.23 × 10⁻⁸N
Explanation:
F= kq²/r²
k= 9×10⁹Nm²/C²
q= 1.6×10⁻¹⁹C
r= 5.29×10⁻¹¹m
F= 9×10⁹× (1.6×10⁻¹⁹)²/ (5.29×10⁻¹¹)²
F = 8.23 × 10⁻⁸N
Answer:
The smallest film thickness is 117 nm.
Explanation:
Light interference on thin films can be constructive or destructive. Constructive interference is dependent on the film thickness and the refractive index of the medium.
For the first interference (surface nearest to viewer), the minimum thickness can be expressed as:
where n is the refractive index of the bubble film.
Therefore,
∴
